01 900ie, unknown mileage on engine, rest of bike has 13k. rough engine/surging when cruising at speed, seems to idle fine. Left side engine case has paper gasket, problem apparent with stock crank sensor shim (1.0 mm) 0.9, 0.8, 0.7, 0.6, and 0.5 mm shim. Currently using the 0.8. Plugs checked for gap and fouling. Replaced crank sensor with one that has 6k on it, same issue. I have/had intermittent starting issues. Rocking the bike back and forth seems to help that for some reason?! I always hear the fuel pump prime. So I was thinking the paper gasket and crank sensor had something to do with it... Valves and fuel map done 4k ago by dealer, belts changed 6k ago...
Bike was fine last season in current form (paper gasket, stock shim, old sensor), I originally thought the problem was a loose chain, but it has not gone away with adjustment so I assumed the intermittent starting might be related.
Any ideas where to look next would be appreciated.
Thank you
Had an issue like yours a few weeks ago with a customer's M620 . . .
Here's the link to said thread, http://www.ducatimonsterforum.org/index.php?topic=73930.0 (http://www.ducatimonsterforum.org/index.php?topic=73930.0)
Good info, to follow up on your thread mine is also an 04 620 but with a 900 transplant... That said, I have Remus high mounts that have been shortened 6 inches with the 01 900 header, no exhaust clog possible... I do have a metal tank, I will check there. Fuel filter maybe? Now that I think of it, this may have coincided with the throttle cable jumping out of throttle body. Maybe have them synced and cable adjusted?

So, you're running the IAW59M ECU?
Check your TPS and trim settings and the fuel filter and lines . . .
I have no idea what ECU I'm running! [laugh] Stock 620 ECU with power commander map done by local ducati shop. Can I check TPS or do I need to bring back to Duc? (I live next door literally, so it's not a big deal to) Fuel filter could probably stand to be replaced along with air filter, both original. What am I looking for on the fuel lines? Clogging?
How long have you had the 900?
Running a 620 map + pc3 seems a "bit heavy " . . would recommend better a 900 reflash and the pc3 for "fine tuning" . . .
Uf fuel/air filter are original then cause could be as simple as fuel filter replacement . . .
But yes, you could next door and have tps checked . . . and tps then reset to correct spec

Stock 620 ECU is a IAW59M. Fuel filter seems likely to me followed by a tank of bad gas. All other items would be digital in nature (like a light switch, either ON or OFF in how they mess with the bike).
I've had the 900 for 6000 miles, all was fine until recently when it got picky about starting. I will bring to the dealer this weekend for sensor check, tps reset, TB sync along with belt change. I will change fuel and air filters (I don't want to pay them for that)

let them do the fuel filter . . .

Why...even a painter can change one of those.

They'll just deny it.
If I fubar, I say it . ..
Brought to the dealer today, had them check all sensors, sync throttle bodies, and adjust throttle cable. No issues found, stated there is surging around 3800-4200 RPM but cant determine the cause. Noted that sprockets are worn and too look for tight spots in the chain. I ordered new sprockets and chain today as well as adjusting timing belts. We shall see if it helps.
Be interesting to see what the AFR is in that rev range.
I have also problems with my 900 ie, sometimes it stalls and clicking(knock) sound before it misfires, feels like one misfire and then runs great again. Is it coils?
Idles fine, before it was runnig great. Sparks changed with 0,7 gap, wires checked.
thanks for replys
Check the regulator/ rectifier wiring where it connects into main harness. My '98 900 burnt these wires & connectors and it had hesitancy/ hiccups at idle and 3-4k rpm's. Replaced burnt connectors and wire portions there, no more issues.
wires were ok, connectors one pin was corrosioned, cleaned that and on short test ride bike was runnig better. Need more testing to see if problem was on the regulator connection.
Hiccups occured again on longer test drive, and bike almost stalls, so problem was'nt fixed. Maybe one of the coil is going to break, I measured coils earlier and coils were ok, cois are pretty expensive to replace if the problem is something else. Any morre ideas to test?
Connectors at coils a nice snug fit, not loose?
Coil connectors checked and I shorten coil wires on both ends 5mm for new/better connection on plug caps.
I ordered and changed California cycleworks coil kit, coils wires plugs and caps. Plug was on the kit NGK DR9EA with 0.6mm gap. Problem wasn't solved, still hicups, stalling. Runnig smoother on new coils so money wasn't totally wasted.
I remember that the problem was before open airbox mod and K&N filter, so that can't cause this? Also tested without powercommander, almost every wire connection cleaned. Any more ideas to test?
Was the PC tuned for an open airbox? Does the miss sound like it is spitting back into the airbox?
I used map from commander site and tested few other maps, same settings on the map. Sounds like it comes from misfire on the horizontal cylinder, but hard to tell. Tested without commander, maybe I should test to tape cover back to the airbox and disconnect commander, what it tells if spitting on the airbox? It also stalls on idle sometimes on traffic lights. Plugs looked clean and good, not oily.
Spitting into the airbox (particularly when its cold and the motor is cold) usually means running lean. My bros M900ie (01 model), actually ran rich down low and at idle. Until we set all the parameters, synched the TBs and played with the throttle bleeds it had a rough fluffy idle. In your case the surging could be lean induced, so try a stock airbox lid and see if it improves (or gets worse). Then you'll know which way to go.
I have also learned that others maps rarely work, unless you are lucky. My bro tried a few maps until he got lucky. We noted the map that worked best and eliminated his symptoms had less fuel down low. In your case it could be lean. So tape up or fit a stock airbox lid to get direction. Dyno time could be in your future.
I'll test other maps and closing airbox. Hope this will fix problems, riding continues on spring cause weather is so cold here, so thanks for tips.
IMHO, you should check TPS setting, if it quits at times on stop lights, it might be that the TPS is at 0° when slightly open and -1° when idling, just numbers to make it a "little more" clear . . .
TPS for your bike should be, according to Brad Black's papers:
M900ie 404mV 2.4°
There was a service bulletin issued for the 900Mie in '00 sometime that revised the TPS idle setting by voltage (not degrees) to 472mV. This corresponds to about 3.1 degrees. As far as I can remember, we ignored this pretty much and kept using 2.4 degrees.
Now, if you have a IAW59M or IAW5.9M[same ECU] then:
900Mie 462mV 2.95°
900Mie '02 3.68°
Now, I will try to link you the tech paper . . Now, question, do you have an electronic diagnostic tool?
edit:
Here is the link to the HOW TO (https://drive.google.com/file/d/0ByWmgp1DWQaiZEx5V3JiemJfVHM/view?usp=sharing)
And a link to a diagnostic tool: http://technoresearch.com/index.php/products/for-single-user/alaris (http://technoresearch.com/index.php/products/for-single-user/alaris)
We used that procedure for my bros M900ie. [thumbsup]
Very informative article.
just basics koko . . . if he has no tool, no can do . . .
went back to read the first few posts . . he has a IAW59M . . . so he is running like an '02 . . . that said, he has a PC3 trying to compensate, IF his trim is too lean, no matter what, the PC3 will NOT be able to compensate the lack of fuel the ECU is sending . . . Thing is, is the ECU re-flashed for a 900 ???
For his setup: airbox and shortened exhaust, his trim should be around 23~24 and CO combined should be between 3.5~4.5%. . .
Goggles, this info is a guideline . . . We need to know what dealer said . . .
Ah a 5.9. I guess the dealer can tune it (or local sponsor?), and then get the PCV tuned to the mods.

if dealer has software + dyno would be optimal, if not, ship have it done for correct engine and then "fiddle with PC3"
